Abstract

La présente invention concerne un procédé de traitement de combustible de four à ciment consistant à introduire un additif dans un élément combustible pour former un mélange combustible. L'élément combustible comprend un carburant combustible produisant du soufre et l'additif comprend un constituant de chaux micronisée. Le procédé consiste en outre à brûler l'élément combustible à l'intérieur d'un four à ciment. Le soufre produit par la combustion du carburant combustible forme, avec la chaux fournie par le constituant de chaux micronisée, des composés du soufre contenant du calcium. Les composés du soufre contenant du calcium tombent sur un lit de clinker en formation au-dessous de la flamme et une partie de ceux-ci peuvent demeurer dans le clinker.
